Abstract

Persistent colonization with Staphylococcus aureus was assessed in 22 nursing home residents. Eighteen residents (82%) remained colonized with the same strain found at baseline; 6 (33%) of 18 residents transiently acquired a new strain. Four residents (18%) acquired a new persistent strain. Residents colonized with methicillin-resistant S. aureus were more likely to acquire a new strain (67%) than were residents colonized with methicillin-susceptible S. aureus (20%) (P = .04).
